The present document applies to Mobile Earth Station (MES) radio equipment which have the following characteristics: 
• the MES has both transmit and receive capabilities and operate in a Satellite-Personal Communications 
Network (S-PCN). An S-PCN MES can be a handheld, portable, vehicle-mounted, host connected, semi-fixed 
or fixed equipment, or can be an element in a multi-mode terminal. It consists of a number of modules with 
associated connections and user interface, or can be a self-contained single unit; 
• these MESs are controlled and monitored by Control Monitoring Functions (CMF). The CMF is outside the 
scope of the present document; 
• if the MES is an element in a multi-mode terminal, unless otherwise stated in the present document, its 
requirements apply only to the S-PCN MES element of the terminal operating in the MSS frequency bands 
given in table 1; 
• the MES is capable in operating in all or part of the frequency bands shown in table 1.
